I find WAR to be pretty easy. For the most part, it's basically DPS with enmity generation.
I usually start off by pulling a group of enemies with tomohawk. ..if it's gonna be a bigger pull, maybe flash. Once I've gotten however many mobs I want, it's spam a couple overpowers and then start going through your "increase enmity" combo (Heavy swing -> skull sunder -> butcher's clock) a couple times on enemies as needed.
If you're tanking one single enemy (like a boss), then use the other combos. For lots of little stuff, work up that wrath and use a steel cyclone.
A little outdated, but this picture shows the basic gist of how to WAR.
